Namechanged as I've told my work colleague already about this and I know she lurks on here. (She was absolutely no help - she's probably still laughing about it...)
Background is that I've been single for a couple of years after discovering he was cheating. I have an 8 year old DD.
I am friends with a small group who I have known for a few years - met through kids at nursery/starting school, etc. We do playdates, dinners, drinks out, whatsapp group which is used constantly, helping each other out, etc. We are close and I value all of their friendships.
For the past few weeks I have felt that one of the group, who I shall refer to as C, has been a bit 'off' with me. Nothing I can really put my finger on - I don't always do the drop off and pick ups at school for my DD, but when I have and I've seen C she hasn't chatted with me like she usually would, and 2 weeks ago 4 of us went out for drinks and I felt that there was a bit of an atmosphere when I was talking to her, although she was polite enough. There are people that I am closer to in the group but C and I have always been very friendly and have done many things with just the 2 of us.
Yesterday, I picked up my DD from school and C's husband was there to pick up their DD. The 4 of us walked back together and we stopped outside C's house to finish our chat briefly, before I carried on up the street. C came to the door but didn't come over although she did wave.
At 4pm I received a text from C which read "Doing her usual, all over XXXXX (her husband's name) and doing that stupid fucking laugh of hers" with a couple of angry emoticons.
I replied back "?" and she immediately sent back "Ooops, sorry! That was meant for L (mutual friend in group, but who is very close to C), talking about someone at work! Sorry, just delete!"
I didn't reply to that and almost straight after I received a text from L asking if I was up for a night out next weekend.
C was talking about me, wasn't she? L also wouldn't usually text me about a night out as it would be sent through the whatsapp chat.
I didn't do the drop off this morning, but C has text me (not in whatsapp group) to ask if I fancy going over to hers tomorrow after school with DD.
I'm not sure how best to respond.
Am I being paranoid in thinking that text was about me?
For the record, I don't know C's husband particularly well. I've chatted with him at group things we've attended and a few times we've walked home together if we've done school pick ups as I've got to pass their house on my way home. I am not attracted to him, and nothing untoward has ever happened or would happen, although I may very well have a stupid fucking laugh!
Any advice? I actually feel really fucking weirded out by this.
